Well I don't know !
Let's get together and work it out.
You said that -2x - 3 = -4x + 3
Add 4x to each side: 2x - 3 = 3
Add 3 to each side: 2x = 6
Divide each side by 2 : x = 3 .
The answer is: B
This problem will only need simple multiplication...
Answer = number of hours per months * months in a year
= 8 2/3 hours / month * 12 months
= 104 hours in 1 year
2 x -2 x 2 = -8
+ 3 x -3 x 3 = -9
- (-2) x 2 = -4
+ 4 x 5 x 2 = 40
- (-2) x 2 = -4
So then -8 + (-9) - (-4) + 40 - (-4) = 31
Glad I can help :)
-14.9 =

- 2.1 (Add 2.1 to both sides)
-12.8 =

(Multiply both sides by 8)
-102.4 = x
